These data were taken over the span of a few days.
Where proteins were measured across different days (e.g. to confirm the consistency of the contrast from day to day), each day has its own subfolder within the folder for that calibrant protein.
In the case of beta amylase (BAmy), data was taken at 2 concentrations (5 and 10 nM), each of which has its own subfolder within the BAmy folder.
